Summary
This study found significant sex differences in cannabis use motives. Male cannabis users reported stronger links between enhancement motives and cannabis-related problems compared to females.
Area of Science:
- Psychology
- Addiction Science
- Cannabis Research
Background:
- Understanding cannabis use motives is crucial for developing effective interventions.
- Previous research has not fully explored sex differences in cannabis use motives and their link to problematic use.
Purpose of the Study:
- To examine sex differences in cannabis use motives.
- To determine if sex moderates the relationship between cannabis use motives and cannabis-related problems.
Main Methods:
- 741 adults reporting past-month cannabis use completed online questionnaires.
- Assessed cannabis use motives (Marijuana Motives Measure) and cannabis-related problems (Marijuana Problem Scale).
- Utilized independent samples t-tests and hierarchical multiple linear regressions.
Main Results:
- Males reported higher motives for coping, conformity, social, and expansion compared to females.
- Significant interactions found between sex and enhancement, expansion, and coping motives regarding problems.
- Male participants showed a stronger association between enhancement motives and problems than females.
Conclusions:
- Cannabis use motives are important targets for interventions for both sexes.
- Enhancement motives may be particularly relevant for males with high problematic cannabis use.
- Sex differences in motives and their relation to problems necessitate tailored intervention strategies.

CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...
